Answer:
Are less reactive
Explanation:
Alkaline-earth metals are to the right of alkali metals.
Answer: kindly check explanation
Explanation:
Given the following :
Measured density of copper block:
8.6+/-0.2 g/cm3
True density = 8.96g/cm3
Standard deviation = 0.4g/cm
a. What is the high and low number of the confidence interval range?
High : 8.6 + 0.2 g/cm3 = 8.8g/cm³
Low : 8.6 - 0.2 g/cm3 = 8.4g/cm³
Does the true value fall within the confidence interval? NO
Actual density = 8.96g/cm³ doses not lie in between (8.4 - 8.8)g/cm³
B.) High and low of the standard deviation range?
High = 8.6 + 0.4 = 9.0g/cm³
Low = 8.6 - 0.4 = 8.2g/cm³
Value falls within range of the true density value of copper block.
8.96g/cm³ falls in-between (8.2-9.0)g/cm³
Answer:
88.1 moles of H₂
Explanation:
Let's make the reaction:
H₂(g) + CO₂(g) → H₂O(g) + CO(g)
Ratio is 1:1
Therefore, 1 mol of hydrogen reacts with 1 mol of carbon dioxide to produce 1 mol of water and 1 mol of carbon monoxide.
In conclusion, 88.1 moles of water must be produced by 88.1 moles of H₂
The reaction can also be written as an equilbrium
H₂(g) + CO₂(g) ⇄ H₂O(g) + CO(g) Kc
Answer:
CH4+4Cl2=CCl4+4HCI
